Überblick
Hydroxylammonium nitrate (HAN) is the salt of hydroxylamine and nitric acid. It is being developed as a potential rocket propellant and is sometimes used in nuclear reprocessing as a plutonium reductant. Nitrite is a toxic compound known to cause methemoglobinemia. (L1137, L1628)

Toxikologische Informationen
Treatment
Methemoglobinemia can be treated with supplemental oxygen and methylene blue 1% solution administered intravenously slowly over five minutes followed by IV flush with normal saline. Methylene blue restores the iron in hemoglobin to its normal (reduced) oxygen-carrying state. (L1613)
Health EffectsNitrate and nitrite poisoning causes methemoglobinemia. Nitrites may cause pregnancy complications and developmental effects. They may also be carcinogenic. (L1137)
Adverse EffectsMethemoglobinemia - The presence of increased methemoglobin in the blood; the compound is classified as secondary toxic effect
Exposure RoutesOral (L1137) ; inhalation (L1137)
Toxicity Summary
Nitrate's toxicity is a result of it's conversion to nitrite once in the body. Nitrite causes the autocatalytic oxidation of oxyhemoglobin to hydrogen peroxide and methemoglobin. This elevation of methemoglobin levels is a condition known as methemoglobinemia, and is characterized by tissue hypoxia, as methemoglobin cannot bind oxygen. (A2450, L1613)
Signs and Symptoms
Nitrate and nitrite poisoning causes methemoglobinemia. Symptoms include cyanosis, cardiac dysrhythmias and circulatory failure, and progressive central nervous system (CNS) effects. CNS effects can range from mild dizziness and lethargy to coma and convulsions. (L1137)
Carcinogen ClassificationIngested nitrate or nitrite under conditions that result in endogenous nitrosation is probably carcinogenic to humans (Group 2A). (L135)

Metabolism/Metabolites
Intake of some amount of nitrates and nitrites is a normal part of the nitrogen cycle in humans. In vivo conversion of nitrates to nitrites can occur in the gastrointestional tract under the right conditions, significantly enhancing nitrates' toxic potency. The major metabolic pathway for nitrate is conversion to nitrite, and then to ammonia. Nitrites, nitrates, and their metabolites are excreted in the urine. (L1137)
